This was just a quick item I whipped up to solve a problem, which was that the cats like their water in nice ceramic bowls but they also like to tip them over. I don’t get it, but whatever.
I used that great 1/4" Chemcast acrylic that you see @marmak3261 using a lot. The first iteration was just a simple open topped box that we put the bowl down into. That worked fine for the cats but my husband kept scraping his fingers on the edges getting the bowl out for refill. The new one works better. Same box design, just flipped over and a hole cut in the top a little smaller than the bowl top edge. No more scraped fingers.
